Whatever changes in the register, you know first.

We read the official company register of Guernsey for the companies on your watchlist; the day a new entry appears, it is in your inbox, linked to the official record.

Two ways to work

Add a company fast, check every fact at its source.

The same record serves both: a quick add for your watchlist or your own forms, and a sourced view for decisions that need evidence.

Quick add

Type the registered number or the name. The company’s details are filled in from the official record, so your list starts clean.

Why it matters

Not knowing is no excuse.

A change in the official register can affect your contract, your loan or your claim from the day it is published. Nobody can follow hundreds of companies by hand.

Once a change is published, you are expected to know about it.

A counterparty whose director changes, whose capital is reduced or who goes into insolvency: you are expected to know. Ulawk checks every day, catches the change, tells you and updates the company profile.

Add your companies
By registered number or by name, or as an Excel list. Companies in other countries by their local company number or LEI.
We read the history
Everything the official record holds is read and turned into a sourced profile.
We check every day
A new entry reaches your inbox the day it appears: its type, a plain summary and a link to the official record. Or into your own systems by webhook.
You decide

Who it's for

For every team that works with company data.

The same register data, four different questions. Each team follows its own list and gets its own alerts.

Banks and finance

Can this person sign this loan for the company?

Current officers at onboarding (KYB), wherever the register publishes them
Ownership and control as filed, with the source
Officer changes, capital cuts and insolvency notices across the loan book; by webhook into your systems

Law firms

Who represents the other side today?

Before signing: who holds office at the counterparty
In disputes: current address, officers, insolvency and liquidation status
In M&A: the history of shareholders, mergers and name changes

Investors and funds

Has anything changed at our portfolio company?

Capital increases and new shareholders as they are filed
Officer changes, share transfers, group links
Before investing: the record history from incorporation and related companies

Companies

Did the supplier we prepaid just go insolvent?

Add your supplier and customer list once from Excel
Liquidation, insolvency, strike-off and frequent officer changes flagged
Check who signs a contract before you sign it

Business parks and incubators follow the companies on their site from one panel, too.

Trust

Every fact linked to its source.

You do not have to wonder whether an AI summary is right. Every line in the profile is linked to the record that says it.

The official record, one click away

The source button opens the official record behind each fact. Information we cannot source does not go into the profile.

No guessing

If the register does not say it, we write “not in the record”. Calculated conclusions are marked as such. Report anything wrong from any line with one click.

Full-name sanctions screening

The company, its officers and shareholders are screened by full name against eight official lists, including the UN, OFAC, EU and UK lists. You confirm a possible hit with date of birth and nationality.

Data protection

Personal identifiers are masked. Your watchlist and notes stay in your account only; connections are encrypted and data is backed up regularly.

Frequently asked

Questions and answers

If your question is not here, write to [email protected].

Which official sources does Ulawk use for Bailiwick of Guernsey?

Official company register of Guernsey. Registered number, current and former names, entity type, status and status date, registration date, registered office, directors and resident agent with appointment dates, registry submissions (date and type) and the annual validation due date. The register keeps no shareholder list; beneficial owners, share capital, financial statements and document contents are not included.

Which law and authorities govern Bailiwick of Guernsey companies?

Crown Dependency with Norman customary law and English common-law influence; companies are governed by the Companies (Guernsey) Law, 2008. Authorities: Company registry: Official company register of Guernsey; Public disclosure: Securities filings of Guernsey; Financial supervision: Guernsey Financial Services Commission (GFSC); Financial intelligence (AML): Financial Intelligence Unit (FIU Guernsey); Beneficial ownership: Official beneficial ownership register of Guernsey. Ulawk shows official records; it is not legal advice.

Can I follow Turkish companies together with Bailiwick of Guernsey companies?

Yes. Turkish companies come from the Turkish Trade Registry Gazette, Bailiwick of Guernsey companies from their official source (official company register of Guernsey); both are in the same panel, and a foreign company can be linked to a Turkish company as its shareholder or officer.

Is the panel available in English?

Yes. Choose Bailiwick of Guernsey from the flag menu and the panel switches to English, with dates and amounts in the local format.

Is this legal advice or a credit rating?

No. Ulawk shows official records with their source. Risk flags are explainable signals from public filings, not a credit score, and nothing here replaces legal advice.
